FortiGate-7000 Load balancing commands

The most notable difference between a FortiGate-7000 and other FortiGates are the commands described in this section for configuring load balancing. The following commands are available:

config load-balance flow-rule config load-balance setting

In most cases you do not have to use these commands. However, they are available to customize some aspects of load balancing.

config load-balance flow-rule

Use this command to add flow rules that add exceptions to how matched traffic is processed by a FortiGate-7000. Specifically you can use these rules to match a type of traffic and control whether the traffic is forwarded or blocked. And if the traffic is forwarded you can specify whether to forward the traffic to a specific FPM or to all FPMs. Unlike firewall policies, load-balance rules are not stateful so for bi-directional traffic, you may need to define two flow rules to match both traffic directions (forward and reverse).

One common use of this command is to control how traffic that is not load balanced is handled. For example, use the following command to send all GRE traffic to the processor module in slot 4. In this example the GRE traffic is received by FortiGate-7000 front panel ports 1C1 and 1C5:

config load-balance flow-rule edit 0 set src-interface 1c1 1c5 set ether-type ip set protocol gre set action forward set forward-slot 4

end

The default configuration includes a number of flow rules that send traffic such as BGP traffic, DHCP traffic and so on to the primary worker. This is traffic that cannot be load balanced and is then just processed by the primary worker.

Syntax

config load-balance flow-rule edit 0 set status {disable | enable}

set src-interface <interface-name> [interface-name>…} set vlan <vlan-id> set ether-type {any | arp | ip | ipv4} set src-addr-ipv4 <ip-address> <netmask> set dst-addr-ipv4 <ip-address> <netmask> set src-addr-ipv6 <ip-address> <netmask> set dst-addr-ipv6 <ip-address> <netmask> set protocol {any | icmp | tcp | udp | igmp | sctp | gre | esp } ah | ospf | pim | vrrp}

set src-l4port <start>[-<end>] set dst-l4port <start>[-<end>]

config load-balance flow-rule                                                                    FortiGate-7000 Load balancing commands

set action {forward | mirror-ingress | mirror-egress | stats | drop} set mirror-interface <interface-name>

set forward-slot {master | all | load-balance | FPM3 | FMP4} set priority <number> set comment <text>

end

status {disable | enable}

Enable or disable this flow rule. Default for a new flow-rule is disable.

src-interface <interface-name> [interface-name>…}

The names of one or more FIM interface front panel interfaces accepting the traffic to be subject to the flow rule.

vlan <vlan-id>

If the traffic matching the rule is VLAN traffic, enter the VLAN ID used by the traffic.

ether-type {any | arp | ip | ipv4 | ipv6}

The type of traffic to be matched by the rule. You can match any traffic (the default) or just match ARP, IP, or

IPv4 traffic.

{src-addr-ipv4 | dst-addr-ipv4 | src-addr-ipv6 | dst-addr-ipv6} <ip-address> <netmask>

The source and destination address of the traffic to be matched. The default of 0.0.0.0 0.0.0.0 matches all traffic.

protocol {any | icmp | tcp | udp | igmp | sctp | gre | esp | ah | ospf | pim | vrrp}

If ether-type is set to ip, ipv4 or ipv6 specify the protocol of the IP or IPv4 traffic to match the rule. The default is any.

{src-l4port | dst-l4port} <start>[-<end>]

Specify a source port range and a destination port range. This option appears for some protocol settings. For example if protocol is set to tcp or udp. The default range is 0-0.

action {forward | mirror-ingress | mirror-egress | stats | drop}

How to handle matching packets. They can be dropped, forwarded to another destination or you can record statistics about the traffic for later analysis. You can combine two or three settings in one command for example you can set action to both forward and stats to forward traffic and collect statistics about it. Use append to add multiple options.

The default action is forward.

The mirror-ingress option copies (mirrors) all ingress packets that match this flow rule and sends them to the interface specified with the mirror-interface option.

config load-balance setting

The mirror-egress option copies (mirrors) all egress packets that match this flow rule and sends them to the interface specified with the mirror-interface option.

set mirror-interface <interface-name>

The name of the interface to send packets matched by this flow-rule when action is set to mirror-ingress or mirroregress.

forward-slot {master | all | load-balance | FPM3 | FPM4 | FPM5 | FPM6}

The worker that you want to forward the traffic that matches this rule to. master forwards the traffic the worker that is operating as the primary worker (usually the FPM module in slot 3. All means forward the traffic to all workers. load-balance means use the default load balancing configuration to handle this traffic. FPM3, FPM4, FPM5 and FPM3 allow you to forward the matching traffic to a specific FPM module. FPM3 is the FPM module in slot 3. FPM4 is the FPM module in slot for. And so on. priority <number>

Set the priority of the flow rule in the range 1 (highest priority) to 10 (lowest priority). Higher priority rules are matched first. You can use the priority to control which rule is matched first if you have overlapping rules.

comment <text>

Optionally add a comment that describes the rule.

config load-balance setting

Use this command to set a wide range of load balancing settings.

config load-balance setting set gtp-load-balance {disable | enable} set max-miss-heartbeats <heartbeats> set max-miss-mgmt-heartbeats <heartbeats> set weighted-load-balance {disable | enable}

set dp-load-distribution-method {round-robin | src-ip | dst-ip | src-dst-ip | src-ipsport | dst-ip-dport | src-dst-ip-sport-dport}

config workers edit 3 set status enable set weight 5

end

end

gtp-load-balance {disable | enable}

Enable GTP load balancing for FortiGate-7000 configurations licensed for FortiOS Carrier.

config load-balance setting                                                                      FortiGate-7000 Load balancing commands

max-miss-heartbeats <heartbeats>

Set the number of missed heartbeats before a worker is considered to have failed. If this many heartbeats are not received from a worker, this indicates that the worker is not able to process data traffic and no more traffic will be sent to this worker.

The time between heartbeats is 0.2 seconds. Range is 3 to 300. 3 means 0.6 seconds, 10 (the default) means 2 seconds, and 300 means 60 seconds. max-miss-mgmt-heartbeats <heartbeats>

Set the number of missed management heartbeats before a worker is considering to have failed. If a management heartbeat fails, there is a communication problem between a worker and other workers. This communication problem means the worker may not be able to synchronize configuration changes, sessions, the kernel routing table, the bridge table and so on with other workers. If a management heartbeat failure occurs, no traffic will be sent to the worker.

The time between management heartbeats is 1 second. Range is 3 to 300 seconds. The default is 20 seconds. weighted-load-balance {disable | enable}

Enable weighted load balancing depending on the slot weight. Use the config slot command to set the weight for each slot.

dp-load-distribution-method {round-robin | src-ip | dst-ip | src-dst-ip | src-ip-sport | dst-ipdport | src-dst-ip-sport-dport}

Set the method used to distribute sessions among workers. Usually you would only need to change the method if you had specific requirements or you found that the default method wasn’t distributing sessions in the manner that you would prefer. The default is src-dst-ip-sport-dport which means sessions are identified by their source address and port and destination address and port. round-robin Directs new requests to the next slot regardless of response time or number of connections. src-ip traffic load is distributed across all slots according to source IP address. dst-ip traffic load is statically distributed across all slots according to destination IP address. src-dst-ip traffic load is distributed across all slots according to the source and destination IP addresses. src-ip-sport traffic load is distributed across all slots according to the source IP address and source port.

dst-ip-dport traffic load is distributed across all slots according to the destination IP address and destination port.

src-dst-ipsport-dport traffic load is distributed across all slots according to the source and destination IP address, source port, and destination port. This is the default load balance schedule and represents true sessionaware load balancing.

config workers

Set the weight and enable or disable each worker. Use the edit command to specify the slot the worker is installed in. You can enable or disable each worker and set each worker’s weight.

config load-balance setting

The weight range is 1 to 10. 5 is average, 1 is -80% of average and 10 is +100% of average. The weights take effect if weighted-loadbalance is enabled.

config workers edit 3 set status enable set weight 5 end

FortiGate-7000 v5.4.3 special features and limitations

This section describes special features and limitations for FortiGate-7000 v5.4.3.

Managing the FortiGate-7000

Management is only possible through the MGMT1 to MGMT4 front panel management interfaces. By default the MGMT1 to MGMT4 interfaces of the FIM modules in slot 1 and slot 2 are in a single static aggregate interface named mgmt with IP address 192.168.1.99. You manage the FortiGate-7000 by connecting any one of these eight interfaces to your network, opening a web browser and browsing to https://192.168.1.99.

Default management VDOM

By default the FortiGate-7000 configuration includes a management VDOM named dmgmt-vdom. For the

FortiGate-7000 system to operate normally you should not change the configuration of this VDOM and this VDOM should always be the management VDOM. You should also not add or remove interfaces from this VDOM.

You have full control over the configurations of other FortiGate-7000 VDOMs.

Firewall

TCP sessions with NAT enabled that are expected to be idle for more than the distributed processing normal TCP timer (which is 3605 seconds) should only be distributed to the master FPM using a flow rule. You can configure the distributed normal TCP timer using the following command:

config system global set dp-tcp-normal-timer <timer>

end

UDP sessions with NAT enabled that are expected to be idle for more than the distributed processing normal UDP timer should only be distributed to the primary FPM using a flow rule.

Link monitoring and health checking

ICMP-based link monitoring for SD-WAN, ECMP, HA link monitoring, and firewall session load balancing monitoring (or health checking) is not supported. Using TCP or UDP options for link monitoring instead. v5.4.3          IP Multicast

IP Multicast

IPv4 and IPv6 Multicast traffic is only sent to the primary FPM module (usually the FPM in slot 3). This is controlled by the following configuration:

config load-balance flow-rule edit 18 set status enable set vlan 0 set ether-type ipv4 set src-addr-ipv4 0.0.0.0 0.0.0.0 set dst-addr-ipv4 224.0.0.0 240.0.0.0 set protocol any set action forward set forward-slot master set priority 5 set comment “ipv4 multicast”

next edit 19 set status enable set vlan 0 set ether-type ipv6 set src-addr-ipv6 ::/0 set dst-addr-ipv6 ff00::/8 set protocol any set action forward set forward-slot master set priority 5 set comment “ipv6 multicast”

end

High Availability

Only the M1 and M2 interfaces are used for the HA heartbeat communication.

When using both M1 and M2 for the heartbeat, FortiGate-7000 v5.4.3 requires two switches. The first switch to connect all M1 ports together. The second second switch to connect all M2 ports together. This is because the same VLAN is used for both M1 and M2 and the interface groups should remain in different broadcast domains.

Using a single switch for both M1 and M2 heartbeat traffic is possible if the switch supports q-in-q tunneling. In this case use different VLANs for M1 traffic and M2 traffic to keep two separated broadcast domains in the switch.

The following FortiOS HA features are not supported or are supported differently by FortiGate-7000 v5.4.3:

• Remote IP monitoring (configured with the option pingserver-monitor-interface and related settings) is not supported
• Active-active HA is not supported l The range for the HA group-id is 0 to 14. l Failover logic for FortiGate-7000 v5.4.3 HA is not the same as FGSP for other FortiGate clusters. l HA heartbeat configuration is specific to FortiGate-7000 systems and differs from standard HA.

Shelf Manager Module

• FortiGate Session Life Support Procotol (FGSP) HA (also called standalone session synchronization) is not supported.

Shelf Manager Module

It is not possible to access SMM CLI using Telnet or SSH. Only console access is supported using the chassis front panel console ports as described in the FortiGate-7000 system guide.

For monitoring purpose, IPMI over IP is supported on SMM Ethernet ports. See your FortiGate-7000 system guide for details.

FortiOS features that are not supported by FortiGate-7000 v5.4.3

The following mainstream FortiOS 5.4.3 features are not supported by the FortiGate-7000 v5.4.3:

• Hardware switch l Switch controller l WiFi controller l WAN load balancing (SD-WAN) l IPv4 over IPv6, IPv6 over IPv4, IPv6 over IPv6 features l GRE tunneling is only supported after creating a load balance flow rule, for example:

config load-balance flow-rule edit 0 set status enable set vlan 0 set ether-type ip set protocol gre set action forward set forward-slot master set priority 3

end

• Hard disk features including, WAN optimization, web caching, explicit proxy content caching, disk logging, and GUIbased packet sniffing. l Log messages should be sent only using the management aggregate interface

IPsec VPN tunnels terminated by the FortiGate-7000

This section lists FortiGate-7000 limitations for IPsec VPN tunnels terminated by the FortiGate-7000:

• Interface-based IPsec VPN is recommended. l Policy based IPsec VPN is supported, but requires creating flow-rules for each Phase 2 selector. l Dynamic routing and policy routing is not supported for IPsec interfaces. l Remote network subnets are limited to /16 prefix.
• IPsec static routes don’t consider distance, weight, priority settings. IPsec static routes are always installed in the routing table, regardless of the tunnel state.

v5.4.3                                                                                                                            SSL VPN

• IPsec tunnels are not load-balanced across the FPMs, all IPsec tunnel sessions are sent to the primary FPM module.
• IPsec VPN dialup or dynamic tunnels require a flow rule that sends traffic destined for IPsec dialup IP pools to the primary FPM module.
• In an HA configuration, IPsec SAs are not synchronized to the backup chassis. IPsec SAs are re-negociated after a failover.

More about IPsec VPN routing limitations

For IPv4 traffic, FortiGate-7000s can only recognize netmasks with 16-bit or 32-bit netmasks. For example:

The following netmasks are supported:

• 34.0.0/24 l 12.34.0.0 255.255.0.0 l 12.34.56.0/21 l 12.34.56.0 255.255.248.0 l 12.34.56.78/32 l 12.34.56.78 255.255.255.255
• 34.56.78 (for single IP addresses, FortiOS automatically uses 32-bit netmasks) The following netmasks are not supported:
• 34.0.0/15 (netmask is less than 16-bit) l 12.34.0.0 255.254.0.0 (netmask is less than 16-bit) l 12.34.56.1-12.34.56.100 (ip range is not supported) l 12.34.56.78 255.255.220.0 (invalid netmask)

SSL VPN

Sending all SSL VPN sessions to the primary FPM module is recommended. You can do this by:

• Creating a flow rule that sends all sessions that use the SSL VPN destination port and IP address to the primary FPM module.
• Creating flow rules that send all sessions that use the SSL VPN IP pool addresses to the primary FPM module. Authentication

This section lists FortiGate-7000 authentication limitations:

• Active authentication that requires a user to manually log into the FortiGate firewall can be problematic because the user may be prompted for credentials more than once as sessions are distributed to different FPM modules. You can avoid this by changing the load distribution method to src-ip.
• FSSO is supported. Each FPM independently queries the server for user credentials.
• RSSO is only supported after creating a load balance flow rule to broadcast RADIUS accounting messages to all FPM modules.

Traffic shaping and DDoS policies

Traffic shaping and DDoS policies

Each FPM module applies traffic shaping and DDoS quotas independently. Because of load-balancing, this may allow more traffic than expected.

Sniffer mode (one-arm sniffer)

One-arm sniffer mode is only supported after creating a load balance flow rule to direct sniffer traffic to a specific FPM module.

FortiGuard Web Filtering

All FortiGuard rating queries are sent through management aggregate interface from the management VDOM (named dmgmt-vdom).

Log messages include a slot field

An additional “slot” field has been added to log messages to identify the FPM module that generated the log.

FortiOS Carrier

FortiOS Carrier is supported by the FortiGate-7000 v5.4.3 but GTP load balancing is not supported.

You have to apply a FortiOS Carrier license separately to each FIM and FPM module to license a FortiGate-7000 chassis for FortiOS Carrier.

Special notice for new deployment connectivity testing

Only the primary FPM module can successfully ping external IP addresses. During a new deployment, while performing connectivity testing from the Fortigate-7000, make sure to run execute ping tests from the primary FPM module CLI.

 

High Availability

FortiGate-7000 supports a variation of active-passive FortiGate Clustering Protocol (FGCP) high availability between two identical FortiGate-7000 chassis. With active-passive FortiGate-7000 HA, you create redundant network connections to two identical FortiGate-7000s and add redundant HA heartbeat connections. Then you configure the FIM interface modules for HA. A cluster forms and a primary chassis is selected.

Example FortiGate-7040

All traffic is processed by the primary (or master) chassis. The backup chassis operates in hot standby mode. The configuration, active sessions, routing information, and so on is synchronized to the backup chassis. If the primary chassis fails, traffic automatically fails over to the backup chassis.

The primary chassis is selected based on a number of criteria including the configured priority, the bandwidth, the number of FIM interface failures, and the number of FPM or FIM modules that have failed. As part of the HA configuration you assign each chassis a chassis ID and you can set the priority of each FIM interface module and configure module failure tolerances and the link failure thresholds.

Before you begin configuring HA

Before you begin, the chassis should be running the same FortiOS firmware version and interfaces should not be configured to get their addresses from DHCP or PPPoE. Register and apply licenses to the each FortiGate-7000 Connect the M1 and M2 interfaces for HA heartbeat communication

before setting up the HA cluster. This includes licensing for FortiCare, IPS, AntiVirus, Web Filtering, Mobile Malware, FortiClient, FortiCloud, and additional virtual domains (VDOMs). Both FortiGate-7000s in the cluster must have the same level of licensing for FortiGuard, FortiCloud, FortiClient, and VDOMs. FortiToken licenses can be added at any time because they are synchronized to all cluster members.

If required, you should configure split ports on the FIMs on both chassis before configuring HA because the modules have to reboot after split ports is configured. For example, to split the C1, C2, and C4 interfaces of an FIM-7910E in slot 1, enter the following command:

config system global set split-port 1-C1 2-C1 2-C4

end

After configuring split ports, the chassis reboots and the configuration is synchronized.

On each chassis, make sure configurations of the modules are synchronized before starting to configure HA. You can use the following command to verify that the configurations of all of the modules are synchronized: diagnose sys confsync chsum | grep all all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e all: c0 68 d2 67 e1 23 d9 3a 10 50 45 c5 50 f1 e6 8e

If the modules are synchronized, the checksums displayed should all be the same.

You can also use the following command to list the modules that are synchronized. The example output shows all four FIM modules have been configured for HA and added to the cluster.

diagnose sys configsync status | grep in_sync

Master, uptime=692224.19, priority=1, slot_1d=1:1, idx=0, flag=0x0, in_sync=1

Slave, uptime=676789.70, priority=2, slot_1d=1:2, idx=1, flag=0x0, in_sync=1

Slave, uptime=692222.01, priority=17, slot_1d=1:4, idx=2, flag=0x64, in_sync=1

Slave, uptime=692271.30, priority=16, slot_1d=1:3, idx=3, flag=0x64, in_sync=1 In this command output in_sync=1 means the module is synchronized with the primary unit and in_sync=0 means the module is not synchronized.

Connect the M1 and M2 interfaces for HA heartbeat communication

HA heartbeat communication between chassis happens over the 10Gbit M1 and M2 interfaces of the FIM modules in each chassis. To set up HA heartbeat connections:

l Connect the M1 interfaces of all FIM modules together using a switch. l Connect the M2 interfaces of all FIM modules together using another switch.

All of the M1 interfaces must be connected together with a switch and all of the M2 interfaces must be connected together with another switch. Connecting M1 interfaces or M2 interfaces directly is not supported as each FIM needs to communicate with all other FIMs.

Connect the M1 and M2 interfaces for HA heartbeat communication

Heartbeat packets are VLAN packets with VLAN ID 999 and ethertype 9890. The MTU value for the M1 and M2 interfaces is 1500. You can use the following commands to change the HA heartbeat packet VLAN ID and ethertype values if required for your switches. You must change these settings on each FIM interface module. By default the M1 and M2 interface heartbeat packets use the same VLAN IDs and ethertypes.

config system ha set hbdev-vlan-id <vlan> set hbdev-second-vlan-id <vlan> set ha-eth-type <eth-type> end

Using separate switches for M1 and M2 is recommended for redundancy. It is also recommended that these switches be dedicated to HA heartbeat communication and not used for other traffic.

If you use the same switch for both M1 and M2, separate the M1 and M2 traffic on the switch and set the heartbeat traffic on the M1 and M2 Interfaces to have different VLAN IDs. For example, use the following command to set the heartbeat traffic on M1 to use VLAN ID 777 and the heartbeat traffic on M2 to use VLAN ID 888:

config system ha

set hbdev-vlan-id 777

set hbdev-second-vlan-id 888   end

If you don’t set different VLAN IDs for the M1 and M2 heartbeat packets q-in-q must be enabled on the switch.

Sample switch configuration for a Cisco Catalyst switch. This configuration sets the interface speeds, configures the switch to allow vlan 999, and enables trunk mode:

##interface config interface TenGigabitEthernet1/0/5 description Chassis1 FIM1 M1 switchport trunk allowed vlan 999

switchport mode trunk

If you are using one switch for both M1 and M2 connections, the configuration would be the same except you would add q-in-q support and two different VLANs, one for M1 traffic and one for M2 traffic.

HA configuration

For the M1 connections:

interface Ethernet1/5 description QinQ Test switchportmode dot1q-tunnel switchport access vlan 888 spanning-tree port type edge

For the M2 connections:

interface Ethernet1/5 description QinQ Test switchport mode dot1q-tunnel switchport access vlan 880 spanning-tree port type edge

HA packets must have the configured VLAN tag (default 999). If the switch removes or changes this tag, HA heartbeat communication will not work and the cluster will form a split brain configuration. In effect two clusters will form, one in each chassis, and network traffic will be disrupted.

HA configuration

Use the following steps to setup the configuration for HA between two chassis (chassis 1 and chassis 2). These steps are written for a set of two FortiGate-7040E or 7060Es. The steps are similar for the FortiGate-7030E except that each FortiGate-7030E only has one FIM interface module.

Each FIM interface module has to be configured for HA separately. The HA configuration is not synchronized among FIMs. You can begin by setting up chassis 1 and setting up HA on both of the FIM interfaces modules in it. Then do the same for chassis 2.

Each of the FortiGate-7000s is assigned a chassis ID (1 and 2). These numbers just allow you to identify the chassis and do not influence primary unit selection.

Setting up HA on the FIM interface modules in the first FortiGate-7000 (chassis 1)

1. Log into the CLI of the FIM interface module in slot 1 (FM01) and enter the following command:

config system ha set mode a-p set password <password> set group-id <id> set chassis-id 1 set hbdev M1/M2

end

This adds basic HA settings to this FIM interface module.

2. Repeat this configuration on the FIM interface module in slot 2 (FIM02).

config system ha set mode a-p set password <password> set group-id <id> set chassis-id 1 set hbdev M1/M2

HA configuration

end

3. From either FIM interface module, enter the following command to confirm that the FortiGate-7000 is in HA mode:

diagnose sys ha status

The password and group-id are unique for each HA cluster and must be the same on all FIM modules. If a cluster does not form, one of the first things to check are groupd-id and re-enter the password on both FIM interface modules.

Configure HA on the FIM interface modules in the second FortiGate-7000 (chassis 2)

1. Repeat the same HA configuration settings on the FIM interfaces modules in the second chassis except set the chassis ID to 2.

config system ha set mode a-p set password <password> set group-id <id> set chassis-id 2 set hbdev M1/M2

end

2. From any FIM interface module, enter the following command to confirm that the cluster has formed and all of the FIM modules have been added to it:

diagnose sys ha status

The cluster has now formed and you can add the configuration and connect network equipment and start operating the cluster. You can also modify the HA configuration depending on your requirements.

Verifying that the cluster is operating correctly

Enter the following CLI command to view the status of the cluster. You can enter this command from any module’s CLI. The HA members can be in a different order depending on the module CLI from which you enter the command.

If the cluster is operating properly the following command output should indicate the primary and backup (master and slave) chassis as well as primary and backup (master and slave) modules. For each module, the state portion of the output shows all the parameters used to select the primary FIM module. These parameters include the number FPM modules that the FIM module is connecting to that have failed, the status of any link aggregation group (LAG) interfaces in the configuration, the state of the interfaces in the FIM module, the traffic bandwidth score for the FIM module (the higher the traffic bandwidth score the more interfaces are connected to networks, and the status of the management links.

HA management configuration

In HA mode, you should connect the interfaces in the mgmt 802.3 static aggregate interfaces of both chassis to the same switch. You can create one aggregate interface on the switch and connect both chassis management interfaces to it.

Managing individual modules in HA mode

When you browse to the system management IP address you connect to the primary FIM interface module in the primary chassis. Only the primary FIM interface module responds to management connections using the system management IP address. If a failover occurs you can connect to the new primary FIM interface module using the same system management IP address.

Managing individual modules in HA mode

In some cases you may want to connect to an individual FIM or FPM module in a specific chassis. For example, you may want to view the traffic being processed by the FPM module in slot 3 of chassis 2. You can connect to the GUI or CLI of individual modules in the chassis using the system management IP address with a special port number.

For example, if the system management IP address is 1.1.1.1 you can browse to https://1.1.1.1:44323 to connect to the FPM module in chassis 2 slot 3. The special port number (in this case 44323) is a combination of the service port, chassis ID, and slot number. The following table lists the special ports for common admin protocols:

FortiGate-7000 HA special administration port numbers

Ch2 slot 6	FPM06	8006	44326	2326	2226	16126

For example:

Firmware upgrade

l To connect to the GUI of the FPM module in chassis 1 slot 3 using HTTPS you would browse to https://1.1.1.1:44313. l To send an SNMP query to the FPM module in chassis 2 slot 6 use the port number 16126.

The formula for calculating the special port number is based on Chassis ID. CH1 = Chassis ID1, CH2 = Chassis ID2. The formula is: service_port x 100 + (chassis_id – 1) x 20 + slot_id.

Firmware upgrade

All of the modules in a FortiGate-7000 HA cluster run the same firmware image. You upgrade the firmware from the GUI or CLI by logging into the primary FIM interface module using the system management IP address and uploading the firmware image.

If uninterruptable-upgrade and session-pickup are enabled, firmware upgrades should only cause a minimal traffic interruption. Use the following command to enable these settings (they should be enabled by default). These settings are synchronized to all modules in the cluster. config system ha set uninterruptable-upgrade enable set session-pickup enable

end

When enabled, the primary FIM interface module uploads firmware to all modules, but in this case, the modules in the backup chassis install their new firmware and reboot and rejoin the cluster and resynchronize.

Then all traffic fails over to the backup chassis which becomes the new primary chassis. Then the modules in the new backup chassis upgrade their firmware and rejoin the cluster. Unless override is enabled, the new primary chassis continues to operate as the primary chassis.

Normally you would want to enable uninterruptable-upgrade to minimize traffic interruptions. But unterruptable-upgrade does not have to be enabled. In fact, if a traffic interruption is not going to cause any problems you an disable unterruptable-upgrade so that the firmware upgrade process takes less time.

Session failover (session-pickup)

Session failover means that after a failover, communications sessions resume on the new primary FortiGate7000 with minimal or no interruption. Two categories of sessions need to be resumed after a failover:

l Sessions passing through the cluster l Sessions terminated by the cluster

Session failover (also called session-pickup) is not enabled by default for FortiGate-7000 HA. If sessions pickup is enabled, while the FortiGate-7000 HA cluster is operating the primary FortiGate-7000 informs the backup FortiGate-7000 of changes to the primary FortiGate-7000 connection and state tables for TCP and UDP sessions passing through the cluster, keeping the backup FortiGate-7000 up-to-date with the traffic currently being processed by the cluster.

Session failover (session-pickup)

After a failover the new primary FortiGate-7000 recognizes open sessions that were being handled by the cluster. The sessions continue to be processed by the new primary FortiGate-7000 and are handled according to their last known state.

Session-pickup has some limitations. For example, session failover is not supported for sessions being scanned by proxy-based security profiles. Session failover is supported for sessions being scanned by flow-based security profiles; however, flowbased sessions that fail over are not inspected after they fail over.

Session terminated by the cluster include management sessions (such as HTTPS connections to the FortiGate

GUI or SSH connection to the CLI as well as SNMP and logging and so on). Also included in this category are IPsec VPN, SSL VPN, sessions terminated by the cluster, and explicit proxy sessions. In general, whether or not session-pickup is enabled, these sessions do not failover and have to be restarted.

Enabling session pickup for TCP and UDP

To enable session-pickup, from the CLI enter:

config system ha set session-pickup enable

end

When session-pickup is enabled, sessions in the primary FortiGate-7000 TCP and UDP session tables are synchronized to the backup FortiGate-7000. As soon as a new TCP or UDP session is added to the primary FortiGate-7000 session table, that session is synchronized to the backup FortiGate-7000. This synchronization happens as quickly as possible to keep the session tables synchronized.

If the primary FortiGate-7000 fails, the new primary FortiGate-7000 uses its synchronized session tables to resume all TCP and UDP sessions that were being processed by the former primary FortiGate-7000 with only minimal interruption. Under ideal conditions all TCP and UDP sessions should be resumed. This is not guaranteed though and under less than ideal conditions some sessions may need to be restarted.

If session pickup is disabled

If you disable session pickup, the FortiGate-7000 HA cluster does not keep track of sessions and after a failover, active sessions have to be restarted or resumed. Most session can be resumed as a normal result of how TCP and UDP resumes communication after any routine network interruption.

If you do not require session failover protection, leaving session pickup disabled may reduce CPU usage and reduce HA heartbeat network bandwidth usage. Also if your FortiGate-7000 HA cluster is mainly being used for traffic that is not synchronized (for example, for proxy-based security profile processing) enabling session pickup is not recommended since most sessions will not be failed over anyway.

Primary unit selection and failover criteria

Primary unit selection and failover criteria

Once two FortiGate-7000s recognize that they can form a cluster, they negotiate to select a primary chassis. Primary selection occurs automatically based on the criteria shown below. After the cluster selects the primary, the other chassis becomes the backup.

Negotiation and primary chassis selection also takes place if the one of the criteria for selecting the primary chassis changes. For example, an interface can become disconnected or module can fail. After this happens, the cluster can renegotiate to select a new primary chassis also using the criteria shown below.

Primary unit selection and failover criteria

How link and module failures affect primary chassis selection

If there are no failures and if you haven’t configured any settings to influence primary chassis selection, the chassis with the highest serial number to becomes the primary chassis.

Using the serial number is a convenient way to differentiate FortiGate-7000 chassis; so basing primary chassis selection on the serial number is predictable and easy to understand and interpret. Also the chassis with the highest serial number would usually be the newest chassis with the most recent hardware version. In many cases you may not need active control over primary chassis selection, so basic primary chassis selection based on serial number is sufficient.

In some situations you may want have control over which chassis becomes the primary chassis. You can control primary chassis selection by setting the priority of one chassis to be higher than the priority of the other. If you change the priority of one of the chassis, during negotiation, the chassis with the highest priority becomes the primary chassis. As shown above, FortiGate-7000 FGCP selects the primary chassis based on priority before serial number. For more information about how to use priorities, see High Availability on page 57.

Chassis uptime is also a factor. Normally when two chassis start up their uptimes are similar and do not affect primary chassis selection. However, during operation, if one of the chassis goes down the other will have a much higher uptime and will be selected as the primary chassis before priorty and serial number are tested.

Verifying primary chassis selection

You can use the diagnose sys ha status command to verify which chassis has become the primary chassis as shown by the following command output example. This output also shows that the chassis with the highest serial number was selected to be the primary chassis.

How link and module failures affect primary chassis selection

The total number of connected data interfaces in a chassis has a higher priority than the number of failed modules in determining which chassis in a FortiGate-7000 HA configuration is the primary chassis. For example, if one chassis has a failed FPM module and the other has a disconnected or failed data interface, the chassis with the failed processor module becomes the primary unit.

For another example, the following diagnose sys ha status command shows the HA status for a cluster where one chassis has a disconnected or failed data interface and the other chassis has a failed FPM module.

hbdevs: local_interface= 2-M1 last_hb_time= 2399.74 status=alive local_interface= 2-M2 last_hb_time= 0.00 status=dead

This output shows that chassis 1 (hostname Chassis-K) is the primary or master chassis. The reason for this is that chassis 1 has a total traffic-bandwidth-score of 30 + 20 = 50, while the total trafficbandwidth-score for chassis 2 (hostname Chassis-J) is 20 + 20 = 40.

The output also shows that both FIM modules in chassis 1 are detecting a worker failure (worker_ failure=1/2) while both FIM modules in chassis 2 are not detecting a worker failure worker_ failure=0/2). The intf-state=(port up)=1 field shows that FIM module in slot 1 of chassis 1 has one more interface connected than the FIM module in slot 1 of chassis 2. It is this extra connected interface that gives the FIM module in chassis 1 slot 1 the higher traffic bandwidth score than the FIM module in slot 1 of chassis 2.

One of the interfaces on the FIM module in slot 1 of chassis 2 must have failed. In a normal HA configuration the FIM modules in matching slots of each chassis should have redundant interface connections. So if one module has fewer connected interfaces this indicates a link failure.

Link failure threshold and board failover tolerance

FIM module failures

If an FIM module fails, not only will HA recognize this as a module failure it will also give the chassis with the failed FIM module a much lower traffic bandwidth score. So an FIM module failure would be more likely to cause an HA failover than a FPM module failover.

Also, the traffic bandwidth score for an FIM module with more connected interfaces would be higher than the score for an FIM module with fewer connected interfaces. So if a different FIM module failed in each chassis, the chassis with the functioning FIM module with the most connected data interfaces would have the highest traffic bandwidth score and would become the primary chassis.

Management link failures

Management connections to a chassis can affect primary chassis selection. If the management connection to one chassis become disconnected a failover will occur and the chassis that still has management connections will become the primary chassis.

Link failure threshold and board failover tolerance

The default settings of the link failure threshold and the board failover tolerance result in the default link and module failure behavior. You can change these settings if you want to modify this behavior. For example, if you want a failover to occur if an FPM module fails, even if an interface has failed you can increase the board failover tolerance setting.

Link failure threshold

The link failure threshold determines how many interfaces in a link aggregation interface (LAG) can be lost before the LAG interface is considered down. The chassis with the most connected LAGs becomes the primary chassis. if a LAG goes down the cluster will negotiate and may select a new primary chassis. You can use the following command to change the link failure threshold:

config system ha set link-failure-threshold <threshold>

end

The threshold range is 0 to 80 and 0 is the default.

A threshold of 0 means that if a single interface in any LAG fails the LAG the considered down. A higher failure threshold means that more interfaces in a LAG can fail before the LAG is considered down. For example, if the threshold is set to 1, at least two interfaces will have to fail.

Board failover tolerance

You can use the following command to configure board failover tolerance.

config system ha set board-failover-tolerance <tolerance>

end

The tolerance range is 0 to 12, and 0 is the default.

Priority and primary chassis selection

A tolerance of 0 means that if a single module fails in the primary chassis a failover occurs and the chassis with the fewest failed modules becomes the new primary chassis. A higher failover tolerance means that more modules can fail before a failover occurs. For example, if the tolerance is set to 1, at least two modules in the primary chassis will have to fail before a failover occurs.

Priority and primary chassis selection

You can select a chassis to become the primary chassis by setting the HA priority of one of one or more of its FIM modules (for example, the FIM module in slot 1) higher than the priority of the other FIM modules. Enter the following command to set the HA priority:

config system ha set priority <number>

end

The default priority is 128.

The chassis with the highest total FIM module HA priority becomes the primary chassis.

Override and primary chassis selection

Enabling override changes the order of primary chassis selection. If override is enabled, primary chassis selection considers priority before chassis up tme and serial number. This means that if you set the device priority higher for one chassis, with override enabled this chassi becomes the primary chassis even if its uptime and serial number are lower than the other chassis.

Enter the following command to enable override.

config system ha set override enable

end

When override is enabled primary unit selection checks the traffic bandwidth score, aggregate interface state, management interface links and FPM module failures first. So any of these factors affect primary chassis selection, even if override is enabled.

IPsec VPN

Adding source and destination subnets to IPsec VPN phase 2 configurations

If your FortiGate-7000 configuration includes IPsec VPNs you should enhance your IPsec VPN Phase 2 configurations as described in this section. If your FortiGate-7000 does not include IPsec VPNs you can proceed with a normal firmware upgrade.

Because the FortiGate-7000 only allows 16-bit to 32-bit routes, you must add one or more destination subnets to your IPsec VPN phase 2 configuration for FortiGate-7000 v5.4.5 using the following command:

config vpn ipsec phase2-interface edit “to_fgt2″So set phase1name <name> set src-subnet <IP> <netmask> set dst-subnet <IP> <netmask>

end Where

src-subnet is the subnet protected by the FortiGate that you are configuring and from which users connect to the destination subnet. Configuring the source subnet is optional but recommended.

dst-subnet is the destination subnet behind the remote IPsec VPN endpoint. Configuring the destination subnet is required.

You can add the source and destination subnets either before or after upgrading to v5.4.5 as these settings are compatible with both v5.4.3 and v5.4.5. However, if you make these changes after upgrading, your IPsec VPNs may not work correctly until these configuration changes are made.

Example basic IPsec VPN Phase 2 configuration

In a simple configuration such as the one below with an IPsec VPN between two remote subnets you can just add the subnets to the phase 2 configuration.

Enter the following command to add the source and destination subnets to the FortiGate-7000 IPsec VPN Phase 2 configuration.

config vpn ipsec phase2-interface edit “to_fgt2″So set phase1name “to_fgt2”

set src-subnet 172.16.1.0 255.255.255.0

Adding source and destination subnets to IPsec VPN phase 2 configurations

set dst-subnet 172.16.2.0 255.255.255.0

end

Example multiple subnet IPsec VPN Phase 2 configuration

In a more complex configuration, such as the one below with a total of 5 subnets you still need to add all of the subnets to the Phase 2 configuration. In this case you can create a firewall address for each subnet and the addresses to address groups and add the address groups to the Phase 2 configuration.

Enter the following commands to create firewall addresses for each subnet.

config firewall address edit “local_subnet_1” set subnet 4.2.1.0 255.255.255.0

next

edit “local_subnet_2” set subnet 4.2.2.0 255.255.255.0

next edit “remote_subnet_3”

set subnet 4.2.3.0 255.255.255.0

next edit “remote_subnet_4”

set subnet 4.2.4.0 255.255.255.0

next edit “remote_subnet_5”

set subnet 4.2.5.0 255.255.255.0 end

And then put the five firewall addresses into two firewall address groups.

config firewall addrgrp edit “local_group” set member “local_subnet_1” “local_subnet_2”

next

edit “remote_group” set member “remote_subnet_3” “remote_subnet_4” “remote_subnet_5”

end

Now, use the firewall address groups in the Phase 2 configuration:

Configuring the FortiGate-7000 as a dialup IPsec VPN server

config vpn ipsec phase2-interface edit “to-fgt2” set phase1name “to-fgt2” set src-addr-type name set dst-addr-type name set src-name “local_group” set dst-name “remote_group”

end

Configuring the FortiGate-7000 as a dialup IPsec VPN server

FortiGate-7000s running v5.4.5 can be configured as dialup IPsec VPN servers.

Example dialup IPsec VPN configuration

The following shows how to setup a dialup IPsec VPN configuration where the FortiGate-7000 acts as a dialup IPsec VPN server.

To configure the FortiGate-7000 as a dialup IPsec VPN server:

Configure the phase1, set type to dynamic.

config vpn ipsec phase1-interface edit dialup-server set type dynamic set interface “v0020” set peertype any set psksecret < password>

end

Configure the phase 2, to support dialup IPsec VPN, set the destination subnet to 0.0.0.0 0.0.0.0.

config vpn ipsec phase2-interface edit dialup-server set phase1name dialup-server set src-subnet 4.2.0.0 255.255.0.0 set dst-subnet 0.0.0.0 0.0.0.0 end

Troubleshooting

To configure the remote FortiGate as a dialup IPsec VPN client

The dialup IPsec VPN client should advertise its local subnet(s) using the phase 2 src-subnet option.

If there are multiple local subnets create a phase 2 for each one. Each phase 2 only advertises one local subnet to the dialup IPsec VPN server. If more than one local subnet is added to the phase 2, only the first one is advertised to the server.

Dialup client configuration:

config vpn ipsec phase1-interface edit “to-fgt7k” set interface “v0020” set peertype any set remote-gw 1.2.0.1 set psksecret <password>

end

config vpn ipsec phase2-interface edit “to-fgt7k” set phase1name “to-fgt7k” set src-subnet 4.2.6.0 255.255.255.0 set dst-subnet 4.2.0.0 255.255.0.0

next edit “to-fgt7k-2” set phase1name “to-fgt7k” set src-subnet 4.2.7.0 255.255.255.0 set dst-subnet 4.2.0.0 255.255.0.0

end

Troubleshooting

Use the following commands to verify that IPsec VPN sessions are up and running.

Use the diagnose load-balance status command from the primary FIM interface module to determine the primary FPM processor module. For FortiGate-7000 HA, run this command from the primary FortiGate-7000. The third line of the command output shows which FPM is operating as the primary FPM.

=========================================

Operating a FortiGate-7000

This chapter describes some FortiGate-7000 general operating procedure.

Failover in a standalone FortiGate-7000

A FortiGate-7000 will continue to operate even if one of the FIM or FPM modules fails or is removed. If an FPM module fails, sessions being processed by that module fail. All sessions are then load balanced to the remaining FPM modules. Sessions that were being processed by the failed module are restarted and load balanced to the remaining FPM modules.

If an FIM module fails, the other FIM module will continue to operate and will become the config-sync master. However, traffic received by the failed FIM module will be lost.

You can use LACP or redundant interfaces to connect interfaces of both FIMs to the same network. In this way, if one of the FIMs fails the traffic will continue to be received by the other FIM module.

Replacing a failed FPM or FIM module

This section describes how to remove a failed FPM or FIM module and replace it with a new one. The procedure is slightly different depending on if you are operating in HA mode with two chassis or just operating a standalone chassis.

Replacing a failed module in a standalone FortiGate-7000 chassis

1. Power down the failed module by pressing the front panel power button.
2. Remove the module from the chassis.
3. Insert the replacement module. It should power up when inserted into the chassis if the chassis has power.
4. The module’s configuration is synchronized and its firmware is upgraded to match the firmware version on the primary module. The new module reboots.
5. Confirm that the new module is running the correct firmware version either from the GUI or by using the config system status

Manually update the module to the correct version if required. You can do this by logging into the module and performing a firmware upgrade.

6. Verify that the configuration has been synchronized.

The following command output shows the sync status of the FIM modules in a FortiGate-7000 chassis. The field in_sync=1 indicates that the configurations of the modules are synchronized.

diagnose sys confsync status | grep in_sy

FIM04E3E16000080, Slave, uptime=177426.45, priority=2, slot_id=1:2, idx=0, flag=0x0, in_sync=1

FIM10E3E16000063, Master, uptime=177415.38, priority=1, slot_id=1:1, idx=1, flag=0x0, in_sync=1

If in_sync is not equal to 1 or if a module is missing in the command output you can try restarting the modules in the chassis by entering execute reboot from any module CLI. If this does not solve the problem, contact Fortinet support.

Replacing a failed module in a FortiGate-7000 chassis in an HA cluster

1. Power down the failed module by pressing the front panel power button.
2. Remove the module from the chassis.
3. Insert the replacement module. It should power up when inserted into the chassis if the chassis has power.
4. The module’s configuration is synchronized and its firmware is upgraded to match the configuration and firmware version on the primary module. The new module reboots.
5. Confirm that the module is running the correct firmware version.

Manually update the module to the correct version if required. You can do this by logging into the module and performing a firmware upgrade.

6. Configure the new module for HA operation. For example:

config system ha set mode a-p set chassis-id 1 set hbdev m1 m2 set hbdev-vlan-id 999 set hbdev-second-vlan-id 990

end

7. Optionally configure the hostname:

config system global set hostname <name>

end

The HA configuration and the hostname must be set manually because HA settings and the hostname is not synchronized.

8. Verify that the configuration has been synchronized.

The following command output shows the sync status of the FIM modules in a FortiGate-7000 chassis. The field in_sync=1 indicates that the configurations of the modules are synchronized.

diagnose sys confsync status | grep in_sy

FIM04E3E16000080, Slave, uptime=177426.45, priority=2, slot_id=1:2, idx=0, flag=0x0, in_sync=1

FIM10E3E16000063, Master, uptime=177415.38, priority=1, slot_id=1:1, idx=1, flag=0x0, in_sync=1

If in_sync is not equal to 1 or if a module is missing in the command output you can try restarting the modules in the chassis by entering execute reboot from any module CLI. If this does not solve the problem, contact Fortinet support.

Installing firmware on an FIM or FPM module from the BIOS using a TFTP server

Use the procedures in this section to install firmware on a FIM or FPM module from a TFTP server after interrupting the boot up sequence from the BIOS.

Installing firmware on an FIM or FPM module from the BIOS using a TFTP server

You might want to use this procedure if you need to reset the configuration of a module to factory defaults by installing firmware from a reboot. You can also use this procedure if you have formatted one or more FIM or FPM modules from the BIOS by interrupting the boot process.

This procedure involves creating a connection between a TFTP server and one of the MGMT interfaces of one of the FIM modules, using a chassis console port to connect to the CLI of the module that you are upgrading the firmware for, rebooting this module, interrupting the boot from the console session, and installing the firmware.

This section includes two procedures, one for upgrading FIM modules and one for upgrading FPM modules. The two procedures are very similar but a few details, most notably the local VLAN ID setting are different. If you need to update both FIM and FPM modules, you should update the FIM modules first as the FPM modules can only communicate with the TFTP server through FIM module interfaces.

Uploading firmware from a TFTP server to an FIM module

Use the following steps to upload firmware from a TFTP server to an FIM module. This procedure requires Ethernet connectivity between the TFTP server and one of the FIM module’s MGMT interfaces.

During this procedure, the FIM module will not be able to process traffic so, if possible, perform this procedure when the network is not processing any traffic.

If you are operating an HA configuration, you should remove the chassis from the HA configuration before performing this procedure.

1. Set up a TFTP server and copy the firmware file to be installed into the TFTP server default folder.
2. Set up your network to allow traffic between the TFTP server and one of the MGMT interfaces of the FIM module to be updated.

If the MGMT interface you are using is one of the MGMT interfaces connected as a LAG to a switch you must shutdown or disconnect all of the other connections in the LAG from the switch. This includes the MGMT interfaces in the other FIM module.

3. Connect the console cable supplied with your chassis to the Console 1 port on your chassis front panel and to your management computer’s RS-232 console port.
4. Start a terminal emulation program on the management computer. Use these settings: Baud Rate (bps) 9600, Data bits 8, Parity None, Stop bits 1, and Flow Control None.
5. Press Ctrl-T to enter console switch mode.
6. Repeat pressing Ctrl-T until you have connected to the module to be updated. Example prompt:

<Switching to Console: FIM02 (9600)>

7. Optionally log into the FIM module’s CLI.
8. Reboot the FIM module to be updated.

You can do this using the execute reboot command from the CLI or by pressing the power switch on the module front panel.

9. When the FIM module starts up, follow the boot process in the terminal session and press any key when prompted to interrupt the boot process.
10. Press C to set up the TFTP configuration.
11. Use the BIOS menu to set the following. Only change settings if required.

[P]: Set image download port: MGMT1 (change if required)

[D]: Set DHCP mode: Disabled

[I]: Set local IP address: A temporary IP address to be used to connect to the TFTP server. This address must not be the same as the chassis management IP address and cannot conflict with other addresses on your network

[S]: Set local Subnet Mask: Set as required for your network.

[G]: Set local gateway: Set as required for your network.

[V]: Local VLAN ID: Use -1 to clear the Local VLAN ID.

[T]: Set remote TFTP server IP address: The IP address of the TFTP server.

[F]: Set firmware image file name: The name of the firmware file to be installed.

12. Press Q to quit this menu.
13. Press R to review the configuration.

If you need to make any corrections, press C and make the changes as required. When the configuration is correct proceed to the next step.

14. Press T to start the TFTP transfer.

The firmware image is uploaded from the TFTP server and installed on the FIM module which then reboots. When it starts up the module’s configuration is reset to factory defaults. The module’s configuration is synchronized to match the configuration of the primary module. The new module reboots again and can start processing traffic.

15. Verify that the configuration has been synchronized.

The following command output shows the sync status of the FIM modules in a FortiGate-7000 chassis. The field in_sync=1 indicates that the configurations of the modules are synchronized.

diagnose sys confsync status | grep in_sy

FIM04E3E16000080, Slave, uptime=177426.45, priority=2, slot_id=1:2, idx=0, flag=0x0, in_sync=1

FIM10E3E16000063, Master, uptime=177415.38, priority=1, slot_id=1:1, idx=1, flag=0x0, in_sync=1

If in_sync is not equal to 1 or if a module is missing in the command output you can try restarting the modules in the chassis by entering execute reboot from any module CLI. If this does not solve the problem, contact Fortinet support.

Uploading firmware from a TFTP server to an FPM module

Use the following steps to upload firmware from a TFTP server to an FPM module. This procedure requires Ethernet connectivity between the TFTP server and one of the MGMT interfaces of one of the FIM modules in the same chassis as the FPM module.

During this procedure, the FPM module will not be able to process traffic so, if possible, perform this procedure when the network is not processing any traffic. However, the other FPM modules and the FIM modules in the chassis should continue to operate normally and the chassis can continue processing traffic.

If you are operating an HA configuration, you should remove the chassis from the HA configuration before performing this procedure.

1. Set up a TFTP server and copy the firmware file to be installed into the TFTP server default folder.
2. Set up your network to allow traffic between the TFTP server and a MGMT interface of one of the FIM modules in the chassis that also includes the FPM module.

You can use any MGMT interface of either of the FIM modules. If the MGMT interface you are using is one of the MGMT interfaces connected as a LAG to a switch you must shutdown or disconnect all of the other connections in the LAG from the switch. This includes the MGMT interfaces in the other FIM module.

Installing firmware on an FIM or FPM module from the BIOS using a TFTP server

3. Connect the console cable supplied with your chassis to the Console 1 port on your chassis front panel and to your management computer’s RS-232 console port.
4. Start a terminal emulation program on the management computer. Use these settings: Baud Rate (bps) 9600, Data bits 8, Parity None, Stop bits 1, and Flow Control None.
5. Press Ctrl-T to enter console switch mode.
6. Repeat pressing Ctrl-T until you have connected to the module to be updated. Example prompt:

<Switching to Console: FPM03 (9600)>

7. Optionally log into the FPM module’s CLI.
8. Reboot the FPM module to be updated.

You can do this using the execute reboot command from the CLI or by pressing the power switch on the module front panel.

9. When the FPM module starts up, follow the boot process in the terminal session and press any key when prompted to interrupt the boot process.
10. Press C to set up the TFTP configuration.
11. Use the BIOS menu to set the following. Only change settings if required.

[P]: Set image download port: The name of the FIM module that can connect to the TFTP server (FIM01 is the FIM module in slot 1 and FIM02 is the FIM module in slot 2).

[D]: Set DHCP mode: Disabled.

[I]: Set local IP address: A temporary IP address to be used to connect to the TFTP server. This address must not be the same as the chassis management IP address and cannot conflict with other addresses on your network.

[S]: Set local Subnet Mask: Set as required for your network.

[G]: Set local gateway: Set as required for your network.

[V]: Local VLAN ID: The VLAN ID of the FIM interface that can connect to the TFTP server:

FIM01 local VLAN IDs

Local VLAN ID         11	12	13	14
FIM02 local VLAN IDs
Interface                MGMT1	MGMT2	MGMT3	MGMT4
Local VLAN ID         21	22	23	24

[T]: Set remote TFTP server IP address: The IP address of the TFTP server.

[F]: Set firmware image file name: The name of the firmware file to be installed.

12. Press Q to quit this menu.
13. Press R to review the configuration.

If you need to make any corrections, press C and make the changes as required. When the configuration is correct proceed to the next step.

14. Press T to start the TFTP transfer.

The firmware image is uploaded from the TFTP server and installed on the FPM module which then reboots.

When it starts up the module’s configuration is reset to factory defaults. The module’s configuration is synchronized to match the configuration of the primary module. The new module reboots again and can start processing traffic.

15. Verify that the configuration has been synchronized.

The following command output shows the sync status of the FIM modules in a FortiGate-7000 chassis. The field in_sync=1 indicates that the configurations of the modules are synchronized.

If in_sync is not equal to 1 or if a module is missing in the command output you can try restarting the modules in the chassis by entering execute reboot from any module CLI. If this does not solve the problem, contact Fortinet support.

 

FIM-7904E interface module

The FIM-7904E interface module is a hot swappable module that provides data, management and session sync/heartbeat interfaces, base backplane switching and fabric backplane session-aware load balancing for a FortiGate-7000 series chassis. The FIM-7904E includes an integrated switch fabric and DP2 processors to load balance millions of data sessions over the chassis fabric backplane to FPM processor modules.

The FIM-7904E can be installed in any FortiGate-7000 series chassis in hub/switch slots 1 and 2. The FIM-7904E provides four Quad Small Form-factor Pluggable plus (QSFP+) interfaces for a FortiGate-7000 chassis. Using a

40GBASE-SR10 multimode QSFP+ transceiver, each QSFP+ interface can also be split into four 10GBASE-SR interfaces.

You can also install FIM-7904Es in a second chassis and operate the chassis in HA mode with another set of processor modules to provide chassis failover protection.

FIM-7904E front panel

The FIM-7904E includes the following hardware features:

• Eight front panel 40GigE QSFP+ fabric channel interfaces (B1 to B8). These interfaces are connected to 40Gbps networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. Using 40GBASESR10 multimode QSFP+ transceivers, each QSFP+ interface can also be split into four 10GBASE-SR interfaces. These interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM7904Es. l Two front panel 10GigE SFP+ interfaces (M1 and M2) that connect to the base backplane channel. These interfaces are used for heartbeat, session sync, and management communication between FIM-7904Es in different chassis. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers, but should not normally be changed. If you use switches to connect these interfaces, the switch ports should be able to accept packets with a maximum frame size of at least 1526. The M1 and M2 interfaces need to be on different broadcast domains. If M1 and M2 are connected to the same switch, Q-in-Q must be enabled on the switch. l Four 10/100/10000BASE-T out of band management Ethernet interfaces (MGMT1 to MGMT4).
• One 80Gbps fabric backplane channel for traffic distribution with each FPM module installed in the same chassis as the FIM-7904E.

 

• One 1Gbps base backplane channel for base backplane with each FPM module installed in the same chassis as the FIM-7904E.
• One 40Gbps fabric backplane channel for fabric backplane communication with the other FIM-7904E in the chassis. l One 1Gbps base backplane channel for base backplane communication with the other FIM-7904E in the chassis. l On-board DP2 processors and an integrated switch fabric to provide high-capacity session-aware load balancing. l One front panel USB port. l Power button. l NMI switch (for troubleshooting as recommended by Fortinet Support). l Mounting hardware. l LED status indicators.

Splitting the FIM-7904E B1 to B8 interfaces

Each 40GE interface (B1 to B8) on the FIM-7904Es in slot 1 and slot 2 of a FortiGate-7000 system can be split into 4x10GBE interfaces. You split these interfaces after the FIM-7904Es are installed in your FortiGate-7000 system and the system us up and running. You can split the interfaces of the FIM-7904Es in slot 1 and slot 2 at the same time by entering a single CLI command. Splitting the interfaces requires a system reboot so Fortinet recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic disruption.

For example, to split the B1 interface of the FIM-7904E in slot 1 (this interface is named 1-B1) and the B1 and B4 interfaces of the FIM-7904E in slot 2 (these interfaces are named 2-B1 and 2-B4) connect to the CLI of your FortiGate-7000 system using the management IP and enter the following command:

config system global set split-port 1-B1 2-B1 2-B4

end

After you enter the command, the FortiGate-7000 reboots and when it comes up:

l The 1-B1 interface will no longer be available. Instead the 1-B1/1, 1-B1/2, 1-B1/3, and 1-B1/4 interfaces will be available. l The 2-B1 interface will no longer be available. Instead the 2-B1/1, 2-B1/2, 2-B1/3, and 2-B1/4 interfaces will be available. l The 2-B4 interface will no longer be available. Instead the 2-B4/1, 2-B4/2, 2-B4/3, and 2-B4/4 interfaces will be available.

You can now connect breakout cables to these interfaces and configure traffic between them just like any other FortiGate interface.

FIM-7904E hardware schematic

The FIM-7904E includes an integrated switch fabric (ISF) that connects the front panel interfaces to the DP2 session-aware load balancers and to the chassis backplanes. The ISF also allows the DP2 processors to distribute sessions amoung all NP6 processors on the FPM modules in the same chassis.

Splitting the FIM-7910E C1 to C4 interfaces

Each 100GE interface (C1 to C4) on the FIM-7910Es in slot 1 and slot 2 of a FortiGate-7000 system can be split into 10 x 10GBE interfaces. You split these interfaces after the FIM-7910Es are installed in your FortiGate-7000 system and the system us up and running. You can split the interfaces of the FIM-7910Es in slot 1 and slot 2 at the same time by entering a single CLI command. Splitting the interfaces requires a system reboot so Fortinet recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic disruption.

For example, to split the C1 interface of the FIM-7910E in slot 1 (this interface is named 1-C1) and the C1 and C4 interfaces of the FIM-7910E in slot 2 (these interfaces are named 2-C1 and 2-C4) connect to the CLI of your FortiGate-7000 system using the management IP and enter the following command:

config system global set split-port 1-C1 2-C1 2-C4

end

After you enter the command, the FortiGate-7000 reboots and when it comes up:

• The 1-C1 interface will no longer be available. Instead the 1-C1/1, 1-C1/2, …, and 1-C1/10 interfaces will be available. l The 2-C1 interface will no longer be available. Instead the 2-C1/1, 2-C1/2, …, and 2-C1/10 interfaces will be available.

By default, the FIM-7920E C1 to C4 interfaces are configured as 100GE QSFP28 interfaces. You can use the following command to convert them to 40GE QSFP+ interfaces. Once converted, you can use the other command below to split them into four 10GBASE-SR interfaces.

 

FIM-7920E hardware schematic

Changing the interface type

For example, to change the interface type of the C1 interface of the FIM-7920E in slot 1 to 40GE QSFP+ connect to the CLI of your FortiGate-7000 system using the management IP and enter the following command:

config system global set qsfp28-40g-port 1-C1

end

The FortiGate-7000 system reboots and when it starts up interface C1 of the FIM-7920E in slot 1 is operating as a 40GE QSFP+ interface .

To change the interface type of the C3 and C4 ports of the FIM-7920E in slot 2 to 40GE QSFP+ enter the following command:

config system global set qsfp28-40g-port 2-C3 2-C4

end

The FortiGate-7000 system reboots and when it starts up interfaces C3 and C4 of the FIM-7920E in slot 2 are operating as a 40GE QSFP+ interfaces.

Splitting the C1 to C4 interfaces

Each 40GE interface (C1 to C4) on the FIM-7920Es in slot 1 and slot 2 of a FortiGate-7000 system can be split into 4 x 10GBE interfaces. You split these interfaces after the FIM-7920Es are installed in your FortiGate-7000 system and the system us up and running. You can split the interfaces of the FIM-7920Es in slot 1 and slot 2 at the same time by entering a single CLI command. Splitting the interfaces requires a system reboot so Fortinet recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic disruption.

For example, to split the C1 interface of the FIM-7920E in slot 1 (this interface is named 1-C1) and the C1 and C4 interfaces of the FIM-7920E in slot 2 (these interfaces are named 2-C1 and 2-C4) connect to the CLI of your FortiGate-7000 system using the management IP and enter the following command:

config system global set split-port 1-C1 2-C1 2-C4

end

After you enter the command, the FortiGate-7000 reboots and when it comes up:

l The 1-C1 interface will no longer be available. Instead the 1-C1/1, 1-C1/2, 1-C1/3, and 1-C1/4 interfaces will be available. l The 2-C1 interface will no longer be available. Instead the 2-C1/1, 2-C1/2, 2-C1/3, and 2-C1/4 interfaces will be available. l The 2-C4 interface will no longer be available. Instead the 2-C4/1, 2-C4/2, 2-C4/3, and 2-C4/4 interfaces will be available.

You can now connect breakout cables to these interfaces and configure traffic between them just like any other FortiGate interface.

NP6 network processors – offloading load balancing and network traffic

The four FPM-7620E NP6 network processors combined with the FIM module integrated switch fabric (ISF) provide hardware acceleration by offloading load balancing from the FPM-7620E CPUs. The result is enhanced network performance provided by the NP6 processors plus the network processing load is removed from the CPU. The NP6 processor can also handle some CPU intensive tasks, like IPsec VPN encryption/decryption. Because of the integrated switch fabric, all sessions are fast-pathed and accelerated.

The FIM-7901E can be installed in any FortiGate-7000 series chassis in hub/switch slots 1 and 2. The FIM-7901E provides thirty-two 10GigE small form-factor pluggable plus (SPF+) interfaces for a FortiGate-7000 chassis.

You can also install FIM-7901Es in a second chassis and operate the chassis in HA mode with another set of processor modules to provide chassis failover protection.

FIM-7901E front panel

The FIM-7901E includes the following hardware features:

• Thirty-two front panel 10GigE SFP+ fabric channel interfaces (A1 to A32). These interfaces are connected to 10Gbps networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers. These interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM-7901Es. l Two front panel 10GigE SFP+ interfaces (M1 and M2) that connect to the base backplane channel. These interfaces are used for heartbeat, session sync, and management communication between FIM-7901Es in different chassis. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers, but should not normally be changed. If you use switches to connect these interfaces, the switch ports should be able to accept packets with a maximum frame size of at least 1526. The M1 and M2 interfaces need to be on different broadcast domains. If M1 and M2 are connected to the same switch, Q-in-Q must be enabled on the switch. l Four 10/100/1000BASE-T out of band management Ethernet interfaces (MGMT1 to MGMT4).
